New pyrrole derivatives used as fungicides, bactericides and insecticides prepared e.g. from novel pyrrole acetic ester and methylation agent

摘要

Pyrrole derivatives (I) as fungicides, bactericides and insecticides are new. Pyrrole derivatives are of formula (I) are new. A = O or NH; E = N or CH; L1 - L3 = H, halo, CN, NO2 or (halo) alkyl(thio), alkoxy, alkylsulfonyl or alkylsulfinyl; G = O or alkyl (both optionally substituted by halo, OH, (halo)alkyl or cycloalkyl), or OCH2, C(R8)=NOCH2, N=C(R8)QCH2, CH(R9)ON=CH2, C(R8)=N-N=CH, QC(R8)=NOCH2, N(R10)C(R8)=NOCH2, OCH2C(R8)=NOCH2, C(=NOR11)C(R8)=NOCH2, C(=NOR11)C(R8)ON=CH or C(=NOR11)C(R8)=N-N=CH; Q = O or S; R8 = alkyl(thio), alkoxy, (di)alkylamino or cycloalkyl (all optionally substituted), H or CN; R9 = alkyl(thio), alkoxy, (di)alkylamino or cycloalkyl (all optionally substituted) or CN; R10 = H, OH, CN, (cyclo)alkyl or alkoxy (both optionally substituted); R11 = H, (halo)alkyl, (halo)alkenyl, alkynyl or aralkyl (optionally substituted); and Z = (cyclo)alkyl, alkenyl, alkynyl, aryl or heterocyclyl (all optionally substituted), and when G = CH2ON=CH, then Z = cycloalkyl, heterocyclyl (both optionally substituted) or substituted aryl. Independent claims are included for new intermediates pyrrole acetic esters of formula (II), (XII) and (XIII) and enamines of formula (III). R12 = alkyl or aryl (both optionally substituted).
